Why? Because people will blame you for getting GWB elected 16 years later? Hell, they're blaming me for Trump, even though I voted for Clinton, just because I wasn't overly enthusiastic about their candidate.
I'm what the rest of the civilized world considers centrist, maybe center left at most. In 20 years, the rest of the US will catch up to where I am now. But here and now, I'm lunatic fringe. That's okay, I'll wait for the establishment Democrats to catch up, like I always do.
